Title: Inheritance in sample array multitree subdivision
Inventor: PHILIP HELLE
IPC: H04N19/593
Filed: 2017-03-03
Abstract: PROBLEM TO BE SOLVED: To provide a coding system for coding an array of information samples each representing a spatially sampled information signal.SOLUTION: A better compromise between encoding complexity and achievable rate distortion ratio, and/or to achieve a better rate distortion ratio is achieved by using multitree sub-divisioning not only in order to subdivide a continuous area, namely the sample array, into leaf regions, but using the intermediate regions also to share coding parameters among the corresponding collocated leaf blocks.EFFECT: By this measure, coding procedures performed in tiles -leaf regions- locally, may be associated with coding parameters individually without having to, however, explicitly transmit the whole coding parameters for each leaf region separately. Rather, similarities may effectively exploited by using the multitree subdivision.SELECTED DRAWING: Figure 12A

Title: Reciprocating four-stroke spark ignition internal combustion engine
Inventor: EDA MASATO
IPC: F01N1/08
Filed: 2017-02-27
Abstract: PROBLEM TO BE SOLVED: To suppress the discharge of unpurified harmful substances in a cold state by achieving the high efficiency of a reduction catalyst, saving resources and reducing costs by preventing the flow-in of secondary air to the reduction catalyst, and by arranging an oxidation catalyst at an upstream side as much as possible, and accelerating the light-off of both the catalysts, in a spark ignition internal combustion engine in which the reduction catalyst is arranged at an upstream side, and the oxidation catalyst is arranged at a downstream side, and which has an exhaust emission control device for supplying the secondary air to both the catalysts.SOLUTION: A main cause that secondary air supplied to a downstream side of a reduction catalyst flows back toward an upstream side in an exhaust pipe, and flows into the reduction catalyst is due to transportation by a positive pressure wave which progresses toward the upstream side from an exhaust pipe end. The positive pressure wave is generated by a negative reflection wave which is generated by the reflection of the positive pressure wave progressing toward the downstream side by the injection of an exhaust gas at the pipe end being a free end, and progresses toward the upstream side. In this invention, a reflector for partially imparting a characteristic of a fixed end to the exhaust pipe end is arranged, the negative reflection wave is canceled by generating a positive reflection wave, and the generation of the positive pressure wave which progresses toward the upstream side is prevented.SELECTED DRAWING: Figure 3
